In this paper, a non-volatile memory cell of Te-based chalcogenide material is proposed and modeled. It is formed by layers of three materials: an insulating material, a conductor and a sensitive material: Te-based ...

Relief Bragg gratings were recorded on the surface of Ga-Ge-S glass samples by interference of two UV laser beams at 351 nm, Scanning force microscopy was used to perform a 3D image analysis of the resulting surface ...

The magneto-optical rotation at room temperature was measured for three Ga:S:La:O chalcogenide glasses at several laser lines in the visible. The first sample was a binary system constituted by 70 mol % Ga2S3 and 30 mol % ...

The electronic band-edges of lead chalcogenides PbY and tin chalcogenides SnY (where Y = S, Se, and Te) are investigated by the means of a full-potential linearized augmented plane wave (FPLAPW) method and the local density ...

In this work we report our achievements in the elaboration and optical characterizations of low-losses suspended core optical fibers elaborated from As2S3 glass. For preforms elaboration, alternatively to other processes ...

Photo-induced phenomena are investigated in new metastable Agx(As20S80)100-x chalcogenide thin-films prepared by the co-evaporation technique. Under irradiation using an Ar laser at 488 nm, periodic ripples structures ...

Elaboration of low-losses highly non linear chalcogenide optical fibers for the generation of efficient non linear effects in the infrared remains a challenge. In recent years, much work has been devoted to the study of ...
